Research output: Contribution to journalConference article


Next generation Internet backbone node architectures are proposed that offer sophisticated QoS support including real time voice, videostreaming, and VPN. The backbone core node, named MSN (Multi-service network) Type-X, has 320 Gb/s throughput and IP V.4/V.6 dual stack forwarding capability. Note that, through the employment of state-of-the art VLSI technology, both V.4 and V.6, OC-192C full wire-rate forwarding performance is achieved for the first time. In addition, sophisticated DiffServ with programmable thousands of virtual queues is also proposed to realize a complete set of hardware. In addition, Type-X uses an ATM emulation technique that can into allow the new packet centric backbone to support conventional services. Finally, the paper describes high-reliability techniques such as newly structured service non-stop software and a firmware upgrade technique. These newly proposed techniques and systems will realize the next generation, real time, high-QoS capability, and VPN IP backbone network to be realized.
